Application led September 18, 1911. Serial No. 650,005.

To all whom it mag/.conceQm Be it known that We, PAUL- Fniennion SGHALLER, subject of the' German Emperor, and CHARLES SUNDT, a subject of the King of Norway, residing at 110 Rue Raumur, Paris, France, have invented certain new and useful Improvements in Smolreonsumers, 'of which the following is a specilication, reference being had therein to the accompanying drawing.

\ This invention relates primarily to the combustion of fuel, has especial reference to smoke consumers, has for-its object economy in the consumption of fuel andthe. avoidance of smoke, soot,-gases or other nnccnsumed products of combustion being emitted from smoke stacks-chimneys and the like'.

The invention consists in certain improvements. which Will be fully disclosed in the folloWing-specication and claim.

'Many devices and methods yhave been proi posed to produce combustion of gases and soot, or rather gases of distillation incompletely burned "issuing from smoke stacks and chimneys. To this endfit has been proposed toheat a'ir preferably in passages,

hollow bodies or other structures. 'But in all these. devices heretofore used, satisfac-l struction which will meet these. indispensible conditions, and provides means placed in the hottest zone of the distilled gases escaping from an industrial, domestic or other furnaceor `lire place, said means comvprising a hollow body of `refractory material, such, as iron, steel, clay, asbestos or Vthe like Which is exposed to said gases and heated to a. very high degree of temperature.

The air taken from the outsideeand entering the hollow body, at the bottom or at the side is very highly heated, is discharged through small criticos or perforations made in Athe body on the side opposite to the orilice of admission. At the discharge orifice Aot the hollow body, the air `penetrates the 55 gases which have not been completely burned and assures the total combustionr thereof,

so that the stack or chimney allows only the non-co1nbustible matter to escape, and 'the smoke or soot is' consumed, or the amount 60 reduced -to almost nothing. The heat of these gases being utilized before their escape from the chimney, the quantity of caloric being sensibly increased offers the advantage of very great economy of combustion,l which amounts to from ifteen to fifty per cent.- To obtain this it is necessary that the hollow body be constructed 'so that the air passing through it is. retarded in its circulation, so as to have time t0 be heated 70 to the temperature of the burning gases and to put it under pressure by its expansion., To obtain these results, the transverse total area of these many orificesv of escape or dis chargev must be less 'than 'the area of the ori- 75 lice or the oritices of admision in a proportion of about 1 to 2. rl-he disposition, of Walls or battles with thel passages alternate in dimensions, gradualir getting larger, Which tinuous passage, the free transverse area of which becomes gradually larger according to the increase of the volume of air under the action of heat. The proportions of this gradual increase of the 'free transverse area' 85 of this continuous' passage formed in the interior of the vhollow body must vary from 4:1 to l8 :1, as comparedv with the orifice of admission in respect to the average temiperature of industrial furnaces, stoves and` In the accompanying drawings, Which forni part of this specilicationz-Figure 1 represents a vertical longitudinal section of one form of our invention.
